I like a bunch of the ideas suggested here. I have one other though. While I love the blue of your pots, as I look at your first photo, the blue pots look out of scale for your front entry. I would use two much larger pots there (? 2 feet tall?) & use the pretty blues ones elsewhere where you can appreciate them up close. Barring that, I would add other taller pots to them to make a larger more imposing grouping. Look again at photo #1 and tell me what you think. I think the pots need to take up more space to add balance to your front entry. It is a lovely front entry, by the way.
